Offset printing is a process to make a print for bulk and commercial purpose as books, brochure, magazines, news paper, packing wrapper materials etc. on high volume 60 % of printing work done by this process there are two types of offset printing each type of offset printing process is same. It is an oil based ink process known as lithography.

1. Sheet feed offset : Sheet print one by one till complete job pass into the press and come out with complete printing, in this process any kinds of stuff can be print like plastic, flat size start 11.692”x8.268” to 28”x40”, paper, plastic and metal etc. per unit cost is higher compare to web offset.

First of all artwork what I have to print in offset design burn into metal plate as “cyan, magenta, yellow and black” each separate metal plate known as CYMK in short as a processed color also and pantone color can be used instead of processed color. Next step is these separate CYMK plate design transfer onto different color rubber blanket rolls different color blanket run with separate color when media (paper) comes to the contact by press between rubber roll and metal plate final print produce.
